Well, in that case is 1116 available to the LPAR? You are shutting down your image, backing it up and restoring to 1116, then bringing up your original and having 1116 be iplable too? Then when you bring back up the original image, you can echo "add device range=1116" >>/proc/dasd/devices, mount and chroot to the path of the mounted device 1116, modify its zipl.conf to use the new addresses as needed, and run zipl. Then exit the chroot and umount the device. Now either address is iplable, just change it in the LPAR's activation profile. If you instead want to ipl the new mirror before you bring it down and backup/restore, do the zipl to point to the new address before you backup/restore, ipl the new one, then mount the old one and zipl it kind of like the reverse of what I just described. If what you actually want is to bring down the image, backup/restore and be able to immediately ipl from two addresses with identical copies of the same data, I'm not aware of any way to do this. You'll need to mount the other dasd and run a zipl for it. ~ Daniel ----------------------------------------------------------------------- This message is the property of Time Inc. or its affiliates.
